This invention intends to provide a deviation measuring apparatus which enables to select a bat capable of bringing a hitting position of a ball to near the center core position of a baseball bat or correct a batting form of a batter by measuring a difference between the hitting position of the ball and the center core position of the bat when the ball is hit with the bat actually. More specifically, there is provided a deviation measuring apparatus for measuring the degree of deviation between the center core position of a baseball bat and the hitting position of a ball by the bat, comprising: a high speed camera for photographing a condition in which the bat strikes the ball; and computing means for obtaining a distance of a difference between the center core position of the bat and the hitting position of the ball.
